Nice little game! The aesthetics are really good, and the music is nice! A few tips: feedback when you get hurt first, it's really unnoticeable. Also, make sure to adjust the environmental hazards hitboxes, they're really easy to avoid, just by walking on the edge of the level. I think the game would benefit A LOT from faster movement. Also, the perspective change idea is nice, but you could have exploited it better. I needed to change it only a couple of times to understand where to go.
Overall, a nice, clean game, nice done!
